The Centre for Health Protection today said it is investigating 351 additional COVID-19 cases, of which more than 340 are locally infected.

Its Communicable Disease Branch Head Dr Chuang Shuk-kwan told a press briefing that most of the local cases involve the Omicron mutant strain.

To stop the potential risk of the virus spreading further, the centre is arranging for residents of buildings where cases are suspected to be related to environmental factors, to undergo quarantine at a quarantine centre.

The buildings include Hing Ping House of Tai Hing Estate, Sau Tai House of Fu Tai Estate and Leung Chi House, Leung King Estate in Tuen Mun, 104 Fuk Wing Street in Sham Shui Po as well as Po Ling House, Po Lam Estate in Tseung Kwan O.

The Government tonight made restriction-testing declarations to cover Hing Cheung House and Hing Tai House of Tai Hing Estate as well as Sun Yuet House and Sun Wai House of Sun Chui Estate in Sha Tin, requiring people in the restricted areas to undergo compulsory testing.

As there were positive sewage test results in Tuen Mun and Wong Tai Sin, Block 1 & 2, Phase 1 in Tai Hing Garden as well as Yue Tung House and Kwai Tung House of Tung Tau (II) Estate are covered in a compulsory testing notice.

In view of the 47 local and 12 linked cases, and one imported and one preliminary positive case, 59 specified premises are also included in the compulsory testing notice.

The Government will set up additional mobile specimen collection stations at Yau Tong Road Playground, Lam Tin Service Reservoir Playground, Tai Po Sports Centre and Tin Ching Community Hall in Tin Shui Wai, while the station at Sin Tat House of On Tat Estate in Kwun Tong will continue to provide a free service for people subject to compulsory testing. 

The mobile specimen collection station at Po Wing Road Sports Centre in Sheung Shui will start operation at 9am today, while the one at Kai Tak East Playground will cease operation.
